To a/ whom it may concern.-

Be it known that I, CLAY M. RUNYAN, a citizen of the United Statesresiding at Elyria, in the -count of Lorain and State of certain newand useful Improvements in Molding-Machines, of which the following is a specification.

This invention relates to molding map chines, and has particular reference to machines of the type used for molding buildingblocks out of concrete, cement mixtures,'&c.

The general objects of the invention are to provide powerful and rapidly-operable means whereby the sides of a mold maybe removed from the molded block simultaneously, to

provide means whereby said sides and the core orcores may be removed simultaneously, and to improve theoperation and control in general, as will appear hereinafter.

With the above objects in view my invention consists, generally speakin in a mold box or chamber having pivotally movable sides and means -for lowering all ofits sides simultaneously.

My invention further consists in the combinat1on,w1tha mold box or chamber having hinged sides, of one or more cores and means for moving said core or cores in and out ofthe core-box simultaneously with the movement of its sides.- v

The invention further consists in the 'combinati'on, with a mold-box and a core therefor, of a removable bottom for said box and means for simultaneously removing said sides and core from the cast and the bottom supporting same, so that the cast may be carried away upon said bottom.

The invention further consists in the'combination, with a stationary'base for the machine, ofthe-core-box, cores, and their oper-- ating mechanism and means vfor tiltin said box, cores, and mechanism into variab e anlgles of inclination.

'The invention further consists in the combination, with the mold-box and its actuating mechanism, of 'means for' counterbalancing the weight thereof upon the operators lever( The invention further consists in thecombination, with a mold-box and its operatin mechanism', of means for varying the size o said box without changing its mode of operation.

The invention lfurther consists in the combination, with'l a casttray and a support p .of end wing-plates 11 11 therefor, of means for providing said tray,

4with a single movement of the operating-lever, with sides and ends to form a mold-box and means for simultaneously projecting a core through the bottom of said tray; and the invention further consists in the novel details of construction and combinations of arts hereinafter described in detail, illustrated in the drawings, and incorporated in v the claims.

In the drawings, Figure 1 is aside eleva- '.tion of a machine embodying my' invention,

part of the base broken away. Fig. 2 is averjtical section taken substantiall on the line Y Y of Fig. 3. Fig. 3 is a top p an View with the cast removed. A` Fig. 4 is a vertical section taken substantially on the line Y Y of Fig. 3,

showing the mold-box in an opened position and the cores lowered.

Referring to the drawings, in which like reference c aracters designate corresponding parts in the several figures, A A are stationary feet or base portions'connected by rods l and 1. The mold-box B and its operating mechanism are supported upon upright channel-brackets C C', having bosses 2 2 .pivoted to bearings 3 3 on the feet A A The lower ends of said Vbrackets have bosses 4' 4', servmovable in curved slots 6 6 in the feet A A. The ends of these slots form stops for the pins 5 5 and limit the arc of rotation of the super- 'ing as threadedsockets for stop-pins 5 5',

structure to the lengths of said slots. On top of the brackets C C is mounted a bed-plate 7,

. fastened, by means of 'bolts 8 passing through with core-openings lai-ger thany the average The sides and ends of moldB consist and side wing-plates 12' 12 preferably provided 'with stren thening-ribs 13, though this is immaterial or the size.

vIOO

fpur ose df my invention.y These wing-plates plates 11 11, pivoted to bearing-brackets 16 16 and 17 17, projecting laterally from the bed-plate 7. In each of the bearing-brackets 16 16 is a series of holes 13 for the hinge or pivot pins 19, connecting-lugs 14 14 with the bearingbrackets 16 16. By moving pivot-pins 19 into different holes the wingplates 12 and 12 may be moved toward or from each other to change the width of the mold-box B, and to enable adjustment of the mold-box to a width less than lthe width of the bed-plate 7 the lugs 14 and 14 are arched over the edges of the bed-plate or made of goosencck form, as shown in Fig. 2.

The bearing-brackets 16 16 and 17 17 are made of sufficient depth to allow room in them for bearings of four shafts 20, 20, 21, and 21, carrying on their ends miter-gears 22 and 23 in mesh with each other and transmitting equal motion to the four shafts, as well :is causing the parallel shafts to rotate in opposite directions. Motion is transmitted from the fourshafts to the wing-plates 1 1, 11, 12, and 12 through alever 24 and corresponding arms 25, 25, and 25, all keyed fast to their respective shafts 20, 20', 21, and 21. The upper ends of said lever and arms are pivoted to links 26 26 and 27 27', pivoted at-their opposite ends between pairs of lugs 28 on the wing-plates. The links 26 are each provided with a series of holes 26 for adjustable pivot-pins 26'", adjustable in conformity with adjustments of pivot-pins 19. The four shafts 29 20 and 21 21 are rotated by I means of a hand-lever 29 ,keyed fast lto a shaft 30, working on a quadrant 29 and provided with the usual' latch-lever 29 ,.guide 29', notches, &c the details of vwhich are wellknown and form no part of this invention. The shaft 3() has keyed fast or otherwise securely fastened thereto a pair of arms 31 31, and said shaft is mounted in bearings consisting of wings or projections 32 32 on channel brackets or supports C C. Motion is transmitted from shaft to the four shafts 20, 20, 21, and 21 through alink33,7pivotedbetween` the ends of arm 31 and to-a lug 34 on the 1ever 24.

' pivoted to the lower ends of links 35 35., iv-

.ed a pair of cores 41 41, fastened by means These cores 4'are nearly of studs or bolts 42. rectangular in cross -sectionand slightly tapered, as shown. While I have shown two cores and suitable apertures therefor, itis-fobvious that any suitable number or only one Itamped in sufficient quantity to ho The inner ends of arms 31 31 rare portion o may be employed without departing from the spirit ofmy invention. While the mold-box is being packed and tamped with plastic material 43 the wing-plates are preferably locked together at the corners b means of pairs of apertured lugs 44 on wlngs 12 12, which straddle single apertured lugs 45 on the end Wing plates '11 11. Pins 46, interlocking said lugs, are preferably. provided with chains 47 secured to the wing-plates to prevent acci ental loss of the pins between molding operations. Other means for locking the corners together may be preferable, and I therefore do not wish to be limited to the lugs and pins.

' When the Wing-plates and cores are down, a considerable weight is thrown upon thefhandlever 29. To counterbalance this weight, I provide counterweights 48, mounted upon arms 49, fixed upon the ends of shafts 21 21. A set-screw 50, havinor threaded engagement with each weight and bearing against the arm 49, provides means for adjusting the weight along the arm to vary its' leverage as necessity may require. The arms 49 are adjusted so that theweights 48 willbe elevated when wing-plates are lowered, and vice versa.

In molding concrete or cement blocks for buildings it is often desirable to make one faceV of the b ook of a liner quality of material than that used in the body of the block. To conveniently accomplish this, I provide for making said face temporarily the bottom of the mold, or substantially so, so that when the facing material isthrown into the mold-box gravity will hold it against the winglate until the backing material is sup ied and Id the facing material. I accomplish this by. tilting the mold-box in the following manner: 51 is a latch looselyY mounted on shaft 30 and normally en aging a pin 52 on the base A. This latch an pin hold the vmold-box and its operating mechanism pivoted to the base at 2., 2, 3, and 3 against tilting to the right, Fig. 2,

while the pins 5 and 5, bearing against the in. either direction. By graspingthe handle 53 of the latch 51 the latter may be disengaged from the 52, which will .permit the upper until the pin 5 comes in contact with the upper end of slot.v The'latch .is also provided with a tread-piece `54, by means of which the operator may kick the latch out of engagement with the pin. `Through the hub of the latch is a.slot.55', into which works a in 56, screwed into thehubof the bearing, an forms a stop for the'latch,lim1ting the amplitude of its swing to the desired length. The lower end of the iatch is beveled, as shown, so as to Ilol ' therefore held vertically 'against movement the machine to swing to the right A IZO ` lever 53 and 4pulling it mrtomatically 'engage the vpin :52 -when the' machine is swungv frorn'an' inclined to its upf right position.. Y y

The operation of m invention is as follows z Assuming'that a bui ding-block or cast is to be formed with a face of better or finer mate'- .rial than the body of the block and that the machine is in the iprosition shown Fig. 2,

the operator will st release thecatch 51,' either by pushing back with his foot the. tread-piece 54 or grasping with his hand the forward. The moldboX B, together with its pivotal supports, levers, vand arms, is then tilted backward to the right to'make the wing-plate 12 the lowermost side. A layer of facing material 43 is then placed within the.A mold .on top of plate 12 andsuificient of the coarser material 43 to hold the facing material in place when the moldis righted. The mold is then returnedl to the position shown in Fig. 2 by simply pulling it forward, the latch 51 automatically engaging the pin 52; The mold is then filled with concrete or plastic material43 and propplates 12, 12,

erly packed and t'amped. Pins 46 are rthen removed to disengage the corners of the mold, the hand-lever r29 pushed toward ythe mold to swing the arms 31 and 31. downward and pull the core 41 downward out of the cast 43.

Simultaneously shaft 21 will be rotated by means of lever 24, connected with arm 31 through link 33. ing connectedy with shafts 20, and 21 through miter-gears 22 and 23, all of said shafts will be rotated, and as arms 25, 25 and 25, as well as lever 24, are fast upon said shafts, said lever and arms will swing 'downward, and with them will be lowered the wing- 11, and 11 into a substantially horizontal position, completely exposing the cast 43 on all sides, 'as on a table. The tray D, upon which the cast rests, is then lifted 0H the base-plate 7 and placed upon the dryingrack .or storage-place for'the casts while they set or harden. Another trayD is then placed upon the base-plate 7 and the wing-plates and core restored to the positions shown in Fig. 2 by simply reversing the movement of lever 29. Another castor building-block is then made in the same manner as above described, and so on. By removing the pivot-pins connecting arms 31 31 with links 35 35 the core-table and its cores may be lifted out of the machine and the latter used for molding solid blocks, Window-caps, door-caps, sills, &c., by simply substituting bottom boards or trays which have no core-openings in them.

` .Another simple manner for adapting my machine for molding solid structures, such as described, which does not involve removing the core-table and its slide-guides vrequires merely the removal ofthe keys shown in Figs.

' 2 and 4, which interlock shaft 30 with the arms 31 31 when the cores are in the posilocking justment also of the pivots connecting lever The motion of shaft 21 be-4 tion shown in lFig. 4. The coreswould then 6 5 ,be disconnected and the wing-plates alone operable by the-lever mechanism. It is ob- 'vious that any other suitable means for intershaft 30v with the arms 31 31 may be employed with special reference to the greatest possible convenience and celerity with which the machine maybe converted from a solid block' to a lhollow -vblock machine or from aholloW-block to a solid-block machine4 inthe-manner described. If it is desired to make buildingfblocks of larger size, pins-19v are removed'and theplu s 14 and 14 pivoted farther apart. This wi l necessitate a read- 24 and arms 25, 25, and 25" with links 26 26 and 27 27lv in suitable holes 26 and the provision of a tray D of 'correspondingly-imcreasedwidth. The openings 8 in the baselate 7 are of such relative sizethat cores 41 arge enough for a block extending to the out'- ermost holes 18 may be substituted, which lwould be accomplished by simply removing the screws 42, fastening cores'41 to the coretable 37. lA single machine constructed in accordance with my invention is therefore adjustable to mold blocks of practically 'every standard size from maximum to minimum'thickness.

VWhile I have shown .the off-bearing late.

or tray D confined between the wing-p ates, it is obvious that it may pass'underneath the lower edges ofthe wing-plates into the bends of the members 14 and 14. This would obviate the necessity of providing a plurality of sizes of trays, and, say,'a twelve-inch tra could therefore be used forten and eight inc blocks, ,&c., thereby ordinarily eHecting a' saving to the user of the machine of from: three to six hundred dollars, as it would not be necessary to carry more than one size of trays. Instead of swinging over the bedroo plate 7 the wing-plates would `then swing over the tray D, so as to clear the edges ofthe tray, all oi' which is clearly obvious without special illustration. It is obvious that the end wing-plates 11 and 11 may be provided with thesame means for later adjustment which are provided for wing-plates 12 an 12 and as numerous vother modifications may be made in the embodiment of my invention withouty departing from the spirit thereof I do not Wish to confine my invention to the specific construction herein shown and described. l n
